Weather in August
Temperature
The dawn of August sees an average high-temperature of a still warm 82.2°F (27.9°C), subtly contrasting with July's 82.9°F (28.3°C). During August, the temperature is averaged to a low of 63.9°F (17.7°C) at night.Heat index
The heat index for August is computed to be a hot 89.6°F (32°C). Enduring exposure and continuous activity might cause a feeling of tiredness and induce heat cramps.It is worth noting that heat index values are gauged for conditions in the shade and light breezes. Uninterrupted exposure to the sun may boost the heat index values by 15 Fahrenheit (8 Celsius) degrees.
Note: The heat index, also known as 'real feel' or 'felt air temperature', is a calculation that merges air temperature and relative humidity to depict the sensation of warmth. The influence of weather is personal, with a diverse population experiencing it differently due to differences in body mass, stature, and degree of activity. Recognize that direct exposure to the sun can escalate the heat effect, potentially adding 15 Fahrenheit (8 Celsius) degrees to the heat index. Heat index values are particularly relevant to children. Youths are typically more endangered than adults since they usually sweat less. Their larger skin surface concerning their smaller bodies and higher heat production due to activity further adds to their vulnerability.
